Description

This variant results in a copy number gain of the genomic region encompassing exon(s) 6 of the PTEN gene. While the exact position of this variant cannot be determined from the data, sub-genic copy number gains are generally in tandem (PMID: 25640679). This variant is predicted to be out-of-frame, and may result in an absent or disrupted protein product. Loss-of-function variants in PTEN are known to be pathogenic (PMID: 9467011, 21194675). A similar copy number variant has been observed in individual(s) with clinical features of Cowden syndrome (PMID: 25669429). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
